Dion Khodagholy, PhD
Associate Professor

Dion Khodagholy is an Associate professor in the Department of Electrical Engineering at Columbia University in New York City. He received his Master’s degree from the University of Birmingham (UK) in Electronics and Telecommunication Engineering. This was followed by a second Master’s degree in Microelectronics at the Ecole des Mines. He attained his PhD in Microelectronics at the Department of Bioelectronics (BEL) of the Ecole des Mines (France). His postdoctoral research at New York University, Langone Medical Center was focused on large-scale cortical acquisition and analysis.

His research explores the interface of electronics and the brain in the context of both applied and discovery sciences, with the ultimate goal of new innovations in device engineering and neuroscience methods to improve diagnosis and treatment of neuropsychiatric disease.

Hyung Joon Shim, PhD
Post-Doctoral Fellow

Hyung Joon Shim is post-doctoral researcher in the Translational Neuroelectronics lab, Department of Electrical Engineering at Columbia University. He received his B.Sc. in Electrical Engineering, Chemical and Biological Engineering from Seoul National University in Korea. After graduation, he joined Prof. Dae-Hyeong Kim's lab at Seoul National University and received Ph.D. with thesis "Development of skin-like electronics using mechanical design strategies and intrinsically stretchable materials". His current research focuses on the development and application of soft electronic materials for neural interface.

Liang is a graduate student working towards a PhD in Biomedical Engineering. He comes from Shenzhen, China. In 2018, Liang received his Bachelor of Science in Electrical & Electronics Engineering from Tel Aviv University, Israel. For his undergraduate project, Liang joined Prof. Yosi Shacham-Diamand’s group as an researcher to perform EIS and Van der Pauw measurements on SAM-enhanced semiconductor devices. At the Translational NeuroElectronics Lab, Liang investigates brain states of neonatal rodents using neural electrophysiology, and build electronics for clinical use. Liang hopes to continue research at the intersection of Electrical Engineering and Neuroscience.

Onni Rauhala
PhD Candidate
Email: o(dot)rauhala(at)columbia(dot)edu

Onni is a graduate student in Columbia University's Electrical Engineering working towards his PhD. Originally from Finland, Onni is a graduate from the College of Biological Sciences at the University of Minnesota, Twin Cities where he got his B.Sc. in neuroscience with a minor in anthropology. His past research experience includes behavioral studies in rodents utilizing optogenetics and electrophysiological methods as well as materials projects for improved histological procedures in neuroscience. Currently, Onni's research work is split between investigating learning and memory in spatial navigation and object recognition using rodent models, and developing  biocompatible implants for neural recordings. 

Duncan Wisniewski
PhD Candidate

Email: djw2169(at)columbia(dot)edu

Duncan is pursuing a PhD in Electrical Engineering at Columbia University. He received a Bachelor of Wireless Engineering as well as a Bachelor of Arts in psychology at Auburn University and received a Master of Science in Electrical Engineering from Columbia university. During his undergraduate degrees he researched satellite communication as a part of the QUEST program and completed a research fellowship focused on motor learning. Duncan's current research involves developing materials and devices for neural interfaces. Duncan hopes to continue researching biocompatible neural devices as he earns his PhD. 

Alexander Ranschaert
PhD Candidate

Email: anr2157(at)columbia(dot)edu

Alexander (Alex) Ranschaert is a graduate student at Columbia University, currently pursuing a PhD in Electrical Engineering. He previously obtained BSc. and MSc. degrees in Electrical Engineering from Ghent University in Belgium, where he specialized in communication systems and machine learning. He also holds an MSc. in Electrical Engineering from Columbia University. He has been working on an organic wireless powering system for compact neural recording devices in rodent models at the Translational NeuroElectronics Lab. In the future, he wishes to continue working  on and improving neural interfaces.
